Be it known thatI, GEORGE W. N. YosT. of Corry,`Penns'ylvania, have invented an linproved Elastic VGa'r-VVheel for Railway Cars or Garriages, ofv which the following is aI specifi-z.

circular, oval, ordiainonded groove betweenl the main wheel and tire, the adaptation ofthe elastic felly to. tthat .groove,and -a wedge- ,The following description and accompanying drawings,`of both which the specifyingletters .refer to the same parts, fully illustrate' the invention, and o f which drawings'- Figure lis a side'viewof the .wh lewheel With allthe partscombined, Fig. 2is a side View of' the yina-in wheel Without the other parts. Fig. 3 is a sectional view 'of the wheel with all the parts combined. Fig.- 4 is a sectional viewof'the main tire andielly or inner tire combined. Fig. 5 is a sectional view'jof the fastening annular disk. Fig. 6, is'a side vvievv1 o f .the elastic felly or inner tire, and

Fig. 7 is a. sectional view-of the periphery of l A is amain Wheel, of cast-iron 'or other in aterial, of any desired style, aboutve 4inches wide-.or thick laterally, and four inches less in diameter than the desiredsize'of va railway-- car'wheel. a is a ange, about an inch wide radially and three-fourths `of an. inch vthick laterally, projectingfrom one side edge of the ma'in vwheel A. 4 is a circular, oval, or diamonded groove from the .inner corner of the flange a tothe middle of theedge of the main wheel A, and about an inch'deep radially.

e is a shoulder, about, an inch vwide radially vtoward the center 'of the main wheel A from the inner line or edge of the groove c.

o is a bevel, from the inner corner of the shoulder e to'theside opposite vto the flange a, of an angle to make the periphery of themain ,wheel A about two inches smaller at one side than. in the middle, next to theshoulder.

A v c is a circular, o`val,or diamonded groove in `thebuter periphery of the disk lB, similartothe groove c in the periphery of -tbe ymain wheelA. a is -a larigev on the disk-B, similar tothe iiangu 'on the mainwheel.

tire, largeenough tu. lsurronudthe main wheel A, and about six inches .wide :laterally and two inches thick rag ldially, with awearing surface and flangesimi common railway-"car wheel, madeof chilled castiron,steel or other material. i

is a circular, oval, or digunonded` groove about three inches widelatei-.ally' and half an inch deep radially.

s and sf 'are shoulders-.one each side of the groove ace-about three-fourths of an inch wide radially, made by the main tirebeing thinner Djs a liexible elastic ring or fellyorinner tirefof leather, cotton, wool, caoutchouc, (india-rubber,) or other materialLdof a circular, oval, ordiamonded ste'mor bo y,\adaptedto 'a curved or a diamonded groove or hollow, -c cl' a1, combinedv of the grooves c, c', and x of the main wheel, disk,y and main tire A, B, and C.

i is, a series of holes' and bolts laterally through the combined'main wheel and disk A B, about 'an inch in diameter, six to ten in number, and the bolts long enough to go through the main wheel and disk A an'd B,

ends.- The parts are combined by putting the mainwheeland disk A and B within the main tire C, with the flange afacing the shoulder s, and

felly or inner tire', D, within the groove or hoh` bythe bolts and nuts and screws through the holes V'disk B, the counterpart of the bevel o on the the diskv B is'iitted to the plane ofside 'of lar .to the ."tread7 and raild auge? of'a/ inthe innerfperiphery of the main-tire C,

between the groove and side edges than at the o groove edges.

and'receive headsandfnuts 'and screws on the low c c x, and are held and fastened together. v

The groove m between the shoulders s and s ofthe main tire C, being narrower than the groove c c of l'the'combined main Wheel, and: disk'A B, will allow radial and lateral vibra` tions of the main tire.

The essential feature of my invention is the A eireulmgoval, or diaxnended forni of the groove c e m and of the elastic felly D, the adyantage being that a lateral pressure will expand radiallysueh a form of elastic felly against every point of the groove w more forcibly and theroughly than it will any other form of elastic felly, which Will allow the renewable tire() to be thinner ande-heaper than any-Other Way. ThereforeJ I limit myself thereto,"aml'only elaiim- Y `2 f oaaeo 1. The combination of a main Wheel. disk, and mainv tire, A, B, andG, when made with a circular, oval, or diamonded groove7 c c w,
